How hard is it to learn English?

My daughter is learning to read, using the phonics system, which is imperfect, but seems to be working.

Helping her learn has made me realise how tricky the English language is.

Take these three words for example:

Lose
Dose
Hose

Three similar looking words, but each with a different pronunciation that would crash any Phonics driven computer.

So good luck to everyone out there learning English. Sorry it's all a bit complicated, but don't blame me, I didn't make up the rules!
